The point to remember is that an operation on a beehive can always take as long as u want it to.  If u want to prove how long it takes, u do one step at a time, with a pause for reflexion between.  If it is a case of 'job & finish', u take off the next roof while the first hive absorbs its smoke - or even move so fast that smoke is hardly needed at all. 
The advantage of these new substances that need only to be drizzled or sprayed is the simplicity of the equipment.  Vaporisers will be used by the mechanically minded larger scale beekeeper.  A quick swish will be used by the hobbyist and deft-handed middle man.  Vive la difference!
